This is a nice-looking living room with smaller rug. Perhaps the key is to frame the rug with sofas / sofa and armchair combo / sofa and the window. And another trick is to fill up the room so the size doesn't look awkward.
Primary Colors: This is an example of primary interior space because the sheets of the bed are red. In addition, the dresser is blue. Thirdly, the pillow on the couch is yellow. Red, yellow, and blue are all primary colors.
